DuPage County Reports First West Nile Case

The DuPage County Health Department reports that a female in her 50s from Downers Grove is the first human case of West Nile Virus (WNV) in DuPage County for 2012. 

Residents are reminded that WNV activity is widespread in DuPage County and the risk of WNV may remain strong for some time this season. WNV is transmitted to people by infected mosquitoes.  The best way to prevent West Nile Virus disease is to take precautions to avoid mosquito bites: 

  • Minimize time spent outdoors between dusk and dawn when mosquitoes are the most active.
  • When outside between dusk and dawn, wear loose-fitting, light-colored clothing that includes long pants, long-sleeved shirts, socks and shoes.
  • Apply insect repellents containing DEET, Picaridin or oil of lemon eucalyptus to exposed skin and clothing.
  • Make sure that doors and windows have tight fitting screens.
  • Remove containers that may hold water to eliminate standing water which serves as a breeding ground for mosquitoes, i.e., discarded tires, cans, ceramic pots.
  • Change water in bird baths at least once per week, and drain and replace water in children's backyard wading pools every four to five days.
  • Make sure that rain gutters, downspouts, swimming pools and pool covers are free of standing water.
  • Keeping grass and weeds cut short to eliminate hiding places for adult mosquitoes.
